Front 21

uranus' orbit and rotation?

Back 21

uranus lays on its side. summer is 21 years of light and winter is 21 years of dark,spring and fall alternate day and night.

Front 22

tempertaure on uranus?

Back 22

2 billion miles from sun,(keplers equation) so far from sun, not huge temperature diffrence from summer to fall.

Front 23

uranus rings?

Back 23

very thin and faint

Front 24

Uranus' diameter

Back 24

32000 miles

Front 25

How far is neptune form the sun?

Back 25

3 billion miles(kepplers equation)

Front 26

Neptunes attributes?

Back 26

virtual twin to uranus,does not ly on side, has some clouds

Front 27

great dark spot

Back 27

hurricane on neptune

Front 28

pertubation

Back 28

disturbances in orbit

Front 29

neptunes natural satilites?

Back 29

numbers will keep growing because it keeps grabbing them. 2 bigger ones.

Front 30

neptunes rings?

Back 30

has them, but are not formed well at all.

Front 31

what year was pluto discovered

Back 31

1930

Front 32

how far away form the sun is pluto?

Back 32

4 billion miles

Front 33

it wasnt until _____ when we really saw pluto through our technologie.

Back 33

1978

Front 34

atmosphere of pluto?

Back 34

made of methane, very thin atmosphere, made up of exaporating methane ice.

Front 35

amount of sun light on pluto?

Back 35

same as the earth when there is a full moon out

Front 36

plutos diameter

Back 36

14000 miles

Front 37

plutos satilites?

Back 37

charon- 7000 miles, 2 smaller ones nix and hydra.

Front 38

why do we think pluto did not start out in the postiion it is in today?

Back 38

pluto has high eccentricity and high inclination

Front 39

inclination?

Back 39

how orbit is tilted relative to earth

Front 40

eccentricity

Back 40

how much orbit differs from a perfect circle.

Front 41

oorts junkyard

Back 41

region of rubble just outside solar system, where we capture comets

Front 42

planet x

Back 42

not discovered, but perturbs pluto, neptune and uranus, have found many bodies but have not picked ont o be the next planet.

Front 43

plutonian planets

Back 43

not terrestial, and not jovian

Front 44

terrestial

Back 44

rocky and metalic

Front 45

jovian

Back 45

hydrogen

Front 46

plutonians

Back 46

icey

Front 47

9 major planets

Back 47

have natural satilites

Front 48

minor planets

Back 48

only differ from major planets because of their size.

Front 49

what is the 7th largest satillite?

Back 49

triton

Front 50

what was the latest discovery on titan by cassinni

Back 50

titan is biologically active and conditions are the same as they were on earth 4 billion years ago.

Front 51

when did astronomers start looking for how our solar sytem began?

Back 51

1970

Front 52

beging of solar system

Back 52

a cloud of gas, mostley hydrogen, must be cold, dense, must be 10x-100x size of universe.

Front 53

trigger

Back 53

gets things started. two options 1. direct colisions of 2 clouds. 2. shockwaves sent from exploding star

Front 54

clouds own gravity made

Back 54

the cloud continusly contract under its own gravity.

Front 55

as cloud condenses

Back 55

center part becomes sphereical and out part becomes disk like. outer part is spinnign faster.

Front 56

central bulge

Back 56

becomes the sun

Front 57

grains

Back 57

look like grain of sand,icey, rockey metalic, begen to solidify...ice could not form close to sun

Front 58

interogenous accretion model

Back 58

model of formation of solar sytem-100 million years

Front 59

where did ice form

Back 59

past mars.

Front 60

plenetesmals- protoplanets

Back 60

same size of todays planets although made entirely of molten

Front 61

grains make ...

Back 61

plantesimals

Front 62

plantestimals make...

Back 62

protoplanets

Front 63

protoplanets make...

Back 63

planets

Front 64

low density materails

Back 64

float to surface, creating layered planets

Front 65

final bombardment

Back 65

occured 3.8-4 billion years ago, left over planettesimals bump into planets

Front 66

jupiter...during final bombardment

Back 66

sling shot icey plentesimals into inner planets

Front 67

final bombardment and rotations

Back 67

all plants got rotation from final bombardment. uranus and pluto in retrograde.
